SPECFECATION forming part of Letters Patent No. 657,152, dated September 4, 1900. Application iilecl September 29, 1899. Serial No. 732,041. (No model.)

To @ZZ whom it may] concern:

Be it known that I, JOSEPH E. AUE, a citizen of the United States, and a resident of the city of New York,

borough of Bronx, county in Can-Fillers,

of which the following is a speci- Iication, reference being had to the accompanying drawings, forming part hereof.

My invention relates to means for filling duid-receptacles, such as cans, with measured or predetermined quantities of fluid, and the means embodying my invention, hereinafter described, have been designed for the purpose of filling the freezing-cans used in the manufacture of ice.

The objects of my invention are to provide a can-filler which shall be automatic in all its operations, shall not waste the water or other filling fluid, shall at all times maintain the fluid-passages full of duid, and shall be readily adjustable and of simple construction,

durable, and

not liable to get out of order;

and to the attainment of these and other desirable objects and advantageous features my invention includes improved means whereby a single valve is caused to perform all of the operations re fluidpassage quired for the control of the through the filler, and my inivention includes various other advantageous features,gall of which will appear from the following description of the accompanying drawings and will be particularly pointed out in the claims.

Figure 1 is of a can-iiller vertical secti which the can-iiller is sition. section on a Fig. 1.

an elevation, partly in section, embodying my inventionand a on of a freezingcan, within placed in operative po- Fig. 2 is a plan view of the same in plane indicated by the line 2 2, Fig. 3 is an enlarged vertical section of the lower part of the ller with the parts as they will appear when the filler is in operative position in contact with the bottom of the can an d the valve open. Fig. 4 is a similar view with the parts as they will appear when the .filler is out of the can.

The can 1 s hown is a freezing-can, such as is ordinarily used in ice-manufacturing establishments.

rlhese cans are lled to a pre- 'from the outlet-casing 5.

determined height with distilled water,which is frozen therein to asolid cake of ice.

The filler has a main tube 3, on which is loosely fitted the fluid-actuated device or float L1. The iiller is shown as provided with a T-head having a stem 7 for the attachment of a flexible tube to connect the filler with the source of fluid-supply and also having a handle S for convenience in handling the filler.

The filler is provided with a single valve, which performs all the operations required for the control of the fluid-passage, such valve in the construction shown being the valve 6, located in an outlet-casing 5 at the 65 exit end of the ller and having a seat 9, formed in such casing and having a downwardly-extending stein 11. A movable foot is also provided fitted to slide vertically in the outlet-casing 5, and a foot-spring 13 is 7o arranged to bear downwardly upon this movable foot and tends to hold the foot in lower position. When, however, the tilleris placed in a can, as shown in Fig. l, the weight of the ller overcomes the spring 13 and the 75 foot is raised to the position shown in Figs. 1 and 3. Y

The valve-stem 11 extends downwardly through an opening in the upper part Aof ra tubular socket 14, formed in said foot 12, and 8o has a head or collar 15, shown as secured upon the lower end of the stem 11, which restricts the downward movement ofthe foot valve 12 relatively to the valve 6 by contact with the upper part of such tubular socket 14 and compels the valve 6 to assume and maintain its lower and closed position when the foot-valve 12 is permitted to assume and maintain its lower position, which occurs at all times except when the weight of the filler 9o is resting upon the foot. A

The Iioat et is connected to the valve 6 thro ugh the iioat-rod 1G,adj ustabl y connected at its upper end to an arm 17, projecting from and shown as secured to the sleeve of the float, and is pivot-ally connected at its lower end to the outer arm 18 of a rock-lever pivoted on a pin 19 in a bracket 20, ext-ending The inner arm 21 of the rock-lever engages the valve-stem 11, 10o

projecting through a slot therein, so that the valve is compelled to move with the rock-arm, and the weight of the iloat when unsupported and free to act will overcome the weight .of the valve and hohl the valve open, and the buoyancy of the float when the can is filled to the predetermined point will close `the valve. The float is not, however, permitted to control the valve except when the filler is in working position, with the foot 12 raised and the spring 13 overcome by the weight of the filler, as the spring 13 when free to act is sufficiently strong to overcome the weight of the float and hold the valve tightly closed.

When, therefore, the iiller is lifted out of a can, the spring 13 will act to close the valve and the parts will assume the position shown in Fig. 4, and the spring 13 will hold the valve thus closed until the filler is placed in operative position in another can. Vhen the filler is placed in a can and the foot 12 is raised by contact with the bottom of the can,

the valve will be lifted and opened by the engagement of the pivoted latch 22 ou the foot 12 with the end of the inner arm 21 of the rock-lever, and thus the fluid-pressure, tending to hold the valve down on its seat, will be overcome by the difference between the resistance of the spring 13 andthe weight or momentum of the iiller, which difference may readily be a force amply suiiicient for such purpose. pushed upwardly its angular movement will cause its end to be withdrawn from over the latch 22, and when the foot reaches its upper position, as shown in Fig. 3, the rocklever arm 21 will be entirely clear of the latch 22, and the valve will therefore be only under the control of the oat and will beheld open by the weight of the float until the can is filled to the predetermined point and will then be closed by the buoyant action of the float. When the filler is lifted out of the can, the foot 12 will return to lower position, the inclined inner face of the latch 22 will pass over the inclined outer face of the end of the rock-lever arm 21, and the latch will be returned by its spring 23 to normal position beneath the end of the rock-lever arm ready to lift the valve when placed in a can.

It will be observed that the foot-spring is assisted by the weight of the foot and valve in overcoming the weight of the float, and the weight of these parts, if made sufficiently great, might be alone relied upon; but I usu. ally prefer to ein ploy a spring, as shown. For the guidance of the valve 6 I have shown ribs 31, formed in the outlet-casing 5 above the seat of the valve,and to provide free fluidpassage through the foot 12 I have shown this foot as composed of an outer tube 32 and the inner tubular socket 14, jointed by ribs 33, the foot-spring 13 resting upon these ribs.

The adjustable connection between the float-rod 16 and the float 4 is shown as formed by two nuts 35 35, working on the threaded end of the rod and clamping against the up- As the rock-lever arm 21 isper and lower surface, respectively, of the floatarm 17.

The frame of the filler is preferably so shaped as to hold the filler upright in the can 4and to shield the float and working parts from injury and is shown as including a top cross-brace 24, clamped to the main tube by a bolt 25 passing through lugs of a split clamp formed in the cross-brace. rlhis cross-brace 24 extends nearly the full width of the interior of the can and has horizontal curved arms 26 extending from the ends thereof around in proximity to the side and end walls of the can. From the middle of the left horizontal 'arm 26 and from the ends of the top cross-brace 25 curved arms 27 extend downwardly and are joined' to a bottom connection 28 upon the main tube 3, and from the middle of the right horizontal arln 26 an arm 29 extends downwardly, isjoined to the bottom connection by a longitudinal brace 30, provided with a guide for the float-rod 16, and is bent inwardly and enters a socket 34 at the end of the bracket 2O of the outlet-casing o.

The only handling required by a filler embodying my invention after it has been connected with the source of duid-supply is the placing of the filler in a can and the removal of the filler from the can. All other operations are automatic. These operations have been above described, but may be now briefly stated in the order of their occurrence. When the ller isl placed in a can in operative position, the foot 12 is raised by contact with the bottom of the can, and thereby the valve 6 is lifted off its seat and moved upward until the foot 12 is disconnected from the valve, and as soon as the valve has left its seat and the fluid has passed beneath it the weight of the fioat 4 will be sufcient to lift the valve, and therefore the valve may be disconnected from the foot at any point after its initial movement, and the upward movement of the valve will be completed by the preponderating weight of the float. W'ith the foot thus raised and disconnected from the valve `the valve is controlled by the -oat, and as soon as the can has been filled to the predetermined height the float will be lifted and the Valve closed. This condition will continue so long as the filleris allowed to remain iu the can. Nhen the filler is lifted out of the can, the tendency of the float to fall, and thereby lift the valve, will be overcome by the foot-spring 13, which will lower the foot and hold the valve closed. When lthe foot reaches lower position, the latch 22 IOO IOS
